Installation - Steel Strong-Portal for Timber Frame Racking Resistance
- The Steel Strong-Portal column should be fixed directly to the concrete foundation.
- DO NOT sit the Steel Strong-Portal on a timber sole plate.
- A DPC is required between the Steel Strong-Portal column and the concrete foundation.
- The concrete foundation should be designed by the engineer repsonsible for the structure to accommodate the hold down anchors and resist the applied loads.
- 1 off 22mm (SSP300) or 28mm (SSP450/SSP600) masonry drill, min. 300mm long.
- 1 off Dust Brush (item code BR17/30).*
- 1 off Dust Pump (item code PUMP).*
- 1 off Resin Dispensing Gun (item code DT380).*
- 1 off 30mm (SSP300) or 36mm (SSP450/SSP600) A/F, Long Length Socket
- 1 off Torque Wrench (min. capacity 150Nm (SSP300) or 200Nm (SSP450/SSP600).
- 1 off SDS 1/4 Hex Drive (SDSD3/8-RB).*
- 1 off T30 drive bit (included).

1a - Position the first Steel Strong-Portal column on top of the foundations in the required position, ensuring the correct orientation of the column with the fixing holes facing internally. Mark the foundation through the holes.
1b - Drill vertical holes to the stated diameter and depth:
SSP300 = Ø22mm x 160mm
SSP450 = Ø28mm x 160mm
SSP600 = Ø28mm x 200mm
1c - Ensure the holes are cleaned thoroughly using a pump and brush.
1d - Install the anchor bolts supplied: AT-HP resin with LMAS threaded rods:
SSP300 = M20 x 210mm
SSP450 = M24 x 210mm
SSP600 = M24 x 250mm
2a - Position the Steel Strong-Portal column over the anchor bolt rods and level by using steel shims and structural grout if required. Plumb and, where necessary, provide temporary bracing, which can be adjacent timber frame panels if already installed.
2b - Install nuts and washers and tighten by hand. Once the AT-HP resin has cured (see cartridge label for cure times) tighten the nut to the recommended torque (M20:150 Nm torque, using torque wrench with a 30mm socket. M24: 200 Nm torque, 36mm socket). Do not over-tighten nuts as this may lead to premature failure.
2c - It is recommended to fix timber studs to the outside of the column. These can be fixed in place using the SDS25112 screws supplied.Note: Where necessary to aid levelling of the column, steel shims are available to order in widths 300, 450 and 600mm and thicknesses 1, 2 and 3.5mm. Contact Simpson Strong-Tie for details.
3a - Place the timber header (not supplied) between the left hand (LH) and right hand (RH) columns. It is recommended to use either Glulam or LVL structural timber for the header. See performance table for minimum size.
3b - Connect the timber header to the column using the ESCR screws provided via the angled holes in the header connection shoe (Fig 3b1). Ensure that the angle between the header and column is 90° (Fig. 3b2) and that there is no gap between the bottom of the header and the section of the column (Fig. 3b3).
